The company was hurt by rising operating expenses, which increased 3% to $15.63 billion last quarter.

Hurt by unfavorable foreign-exchange fluctuations, Amazon.com said its operating income slumped 26% year-over-year to $79 million. That was well above the Street's view of $51.8 million and the company’s guidance for a loss of $340 million to a gain of $10 million.

Operating cash flow soared 41% to $4.53 billion for the trailing 12 months, while free cash flow plunged 76% to $265 million over that span.

Amazon.com warned it expects to post an operating loss of between $65 million and $440 million, which compares unfavorably with forecasts for a gain of $71.1 million. Management said sales are seen ranging between $15.45 billion to $17.15 billion, the midpoint of which is below estimates on Wall Street for $16.98 billion.

Non-GAAP operating income is seen ranging between a loss of $100 million and a profit of $275 million, which is below the Street’s view of $402 million.

Wall Street punished Seattle-based Amazon.com for the latest news, driving its stock down 2.10% to $294.03 in after-hours trading.
